("Filtronic", the "Company" or the "Group")

HALF YEAR RESULTS FOR THE SIX MONTHS ENDED 30 NOVEMBER 2025

Filtronic plc (AIM: FTC), the designer and manufacturer of products and sub-systems for the aerospace, defence, telecoms infrastructure, space and critical communications markets, is pleased to announce its half year results for the six months ended 30 November 2025 ("H1 2026").

The Group delivered an encouraging first-half performance, with financial results in line with the Board's expectations and very positive momentum in new business activity. Revenue was similar to the record prior period which benefited from peak delivery on major space programmes. H1 2026 displayed a more balanced delivery profile with profitability reflecting deliberate and targeted investment in people, facilities and product development to position the business for accelerated growth. Cash generation remained strong, enabling continued strategic investment and leaving the Group well positioned to capitalise on a rapidly expanding Defence and Space pipeline. Following strong order levels in H1 2026, Filtronic has entered the second half of FY2026 with a record order book, providing clear visibility and confidence in our strategy and sustained long- term growth.

Financial Highlights                                                                                                                                              

¹ Adjusted EBITDA is earnings before interest, taxation, depreciation, amortisation, share-based payments and exceptional items.

Significant contract momentum and diversification of revenue mix

Continued execution of five-year growth strategy

Outlook

Nat Edington, Chief Executive Officer, commented: "The first half of the year demonstrated the strength of Filtronic's positioning in markets where performance, reliability and security are mission critical. Demand across our space, aerospace and defence markets remains robust, and our focus on high-frequency RF technologies continues to differentiate us with customers operating in the most demanding environments.

With a record order book, increasing customer diversification and the business now operating at greater scale, we have entered the second half confident of continuing our planned growth."

¹ As at 2 February 2026, the Board understands that market expectations for FY2026, based on published analyst forecasts, are for revenue of £55.5m, within a range of £54m to £56.9m and EBITDA of £10.9m, within a range of £10.1m to £12.0m.

Chief Executive's review

H1 FY2026 has been one of strong strategic execution for Filtronic. We have continued to build on our technological leadership and long-standing customer relationships, while investing to support the next phase of growth. The momentum achieved during the half reflects both the scale of the opportunity in our core markets and the progress we are making in building a business capable of supporting sustained diversified growth.

Market dynamics

We operate in markets where performance, reliability and security are mission-critical, and where demand remains robust. Our core markets of space and defence continue to be supported by sustained satellite deployment activity, increased defence expenditure and growing requirements for secure, high-frequency communications. Customer programmes are increasingly focused on higher spectrum solutions and advanced technologies such as gallium nitride ("GaN"), areas where Filtronic has established a market leading technical capability. As a result, we continue to see active engagement across both new and existing customers, reinforcing our positioning within these strategically important markets.

Financial performance

In the first half of the year, as expected, revenue was broadly in line with the prior period at £25.3m (H1 FY2025: £25.6m). As previously communicated, deliberate and targeted investment in the business, to achieve sustainable long-term revenue growth in high-growth markets, meant profits were lower in the period than the same period last year with adjusted EBITDA of £5.1m (H1 2025: £8.7m) and an operating profit of £2.6m (H1 2025: £6.8m).

As highlighted in previous announcements, the weaker USD had an impact on revenues in the period, given the Group's significant exposure to North America. At the same time, the benefits of last year's strategic investments are starting to be realised, including the expansion of our engineering teams, the opening of our new facility, and the associated increase in production capacity to support future growth. While these initiatives have increased costs in the short term, they establish a strong foundation for sustainable growth and are critical to strengthening the business for the years ahead.

We ended the Period in a strong financial position, with £10.5m of cash in the bank (31 May 2025: £14.5m), having self-financed the capital project to relocate to the larger headquarters and manufacturing site at Sedgefield, and £8.2m in net cash when excluding right of use property leases (31 May 2025: £5.1m).

Strategic progress

The Period was characterised by significant contract momentum and further deepening of key customer relationships. We secured our two largest contract awards with SpaceX, which strengthened our strategic relationship, of which the second contract will start to be delivered in FY2027. On top of this, the second award worth £47.3m, represents the first deployment of our next generation, proprietary GaN E-band product. These wins demonstrate not only confidence in our products, but also in our ability to deliver consistently, at scale and to demanding specifications.

Alongside this, we continued to make strong progress in diversifying our customer base, as demonstrated by a €7.0m (£5.8m) multi-year contract with a leading European aerospace manufacturer. This contract is to supply RF assemblies for integration into a major Low Earth Orbit satellite constellation programme. In addition, we secured a £13.4m contract with a leading European defence prime for the supply of high-performance active components for the next phase of a long-standing electronic sensor programme. Post-period end, we also secured an Authorisation to Proceed, for an expected £11.0m contract, for a follow-on contract that gives order cover for a further two-years with the same European defence prime.

Engagement with major primes, within space and defence, and government organisations is increasing, supported by our sovereign accreditations, manufacturing capabilities and proven track record in high-reliability RF systems. This diversification is an important strategic priority, reducing customer concentration over time while also expanding our addressable market.

We moved into our new headquarters in Sedgefield in November and will be periodically migrating our manufacturing lines over the next few months as customer programmes allow for transfer. The official opening of the building will take place on 26 February 2026 as we celebrate our new state-of-the-art facility enabling us to scale and futureproof the business operations for the next phase of growth.

Innovation

Innovation is central to Filtronic's long-term growth strategy. As demand for high-speed data continues to accelerate, communications systems are increasingly moving into higher RF bands to enhance performance and alleviate congestion at lower frequencies.

The V-band and W-band regions of the RF spectrum offer substantial potential for next-generation, high-capacity wireless communications. V-band, in particular, provides extensive bandwidth and is expected to be widely adopted by satellite communication companies.

Filtronic is at the forefront of developing the critical enabling technologies needed to unlock the full potential of these higher-frequency bands. Our Cerus range of solid-state power amplifiers ("SSPAs") delivers class-leading power performance across V-band, E-band and W-band frequencies. As bandwidth and data demands continue to grow, these SSPAs are well positioned to support a wide range of high-performance wireless and space applications.

This technology leadership is underpinned by strong execution against our product roadmap. The successful development and initial deployment of our GaN E-band product, represent a step change in performance and reinforces the progress being made across our innovation programme. Further product launches are planned for calendar year 2026, targeting emerging opportunities in space ground systems. Our family of very high-power V-band amplifiers being released in FY2026 will open up opportunities in medium earth orbit ("MEO") and geostationary ("GEO") for the business for the first time. In addition, the recent award of £1.2 million in funding from the UK Space Agency's National Space Innovation Programme, supporting the development of a 550W Ka-band solid-state power amplifier, further reinforces our intent to capitalise on the significant opportunity emerging within the global space ecosystem.

People and operations

The progress delivered by our teams across the business in the first half of the year has been instrumental in strengthening both our execution capability and commercial momentum. Investment in our commercial teams is enabling earlier and more effective engagement across programme lifecycles, enhancing alignment with major primes and government customers, whilst also accelerating the expansion of our opportunity pipeline.

This commercial momentum is matched by the continued scaling of our engineering capability. The successful expansion of our Cambridge operation in FY2025 now supports multiple concurrent development programmes, while the self-funded relocation to a larger headquarters and manufacturing facility in Sedgefield provides materially increased production capacity and capability.

Together, these advances reflect a more integrated, higher-value organisation, better positioned to capture complex, global opportunities. They also support our strategic progression up the value chain, expanding our expertise beyond RF into digital, software, and system-level solutions.

Outlook

The first half of the year has demonstrated that the investments made in both capacity, capability and technology, are delivering tangible commercial successes. With a record order book, including new and diverse customer contract wins, we have entered H2 in a strong position and are confident of meeting market expectations for the full year.

Over the longer term, customers are expressing a growing need for high-frequency, secure, and resilient communications infrastructure across many platforms which provide the Group with supportive structural growth drivers across its key markets. With our expanded manufacturing capacity now fully operational, we believe we have exciting products and capabilities to match this growing need.

Notes to the Condensed Financial Statements

1    Company information

      Filtronic plc is a company registered and domiciled in the United Kingdom and is listed on the AIM market of the London Stock Exchange. The Company's registered number is 2891064. The address of the Company's registered office is Filtronic plc, Plexus 1, NETPark, Thomas Wright Way, Sedgefield, County Durham, TS21 3FD.

   Copies of the Company's Annual Report and interim financial report are available from the Company's registered office or the Company's website at www.filtronic.com.

2    Basis of preparation

      Whilst the financial information included in this preliminary statement has been prepared on the basis of the requirements of IFRSs in issue, this statement does not itself contain sufficient information to comply with IFRS.

      These financial results for the six months ended 30 November 2025 do not comprise statutory accounts within the meaning of Section 434 of the Companies Act 2006. The interim report should be read in conjunction with the Annual Report 2025, which includes annual financial statements for the year ended 31 May 2025. Those accounts have been reported on by the Company's auditor and delivered to the registrar of companies. The report of the auditor was (i) unqualified (ii) did not include a reference to any matters to which the auditor drew attention by way of emphasis without qualifying their report, and (iii) did not contain a statement under section 498 (2) or (3) of the Companies Act 2006.

     The condensed consolidated financial statements for the six months ended 30 November 2025 consolidate the financial statements of the Company and all of its subsidiaries (together referred to as the "Group"). Transactions between Group companies, which are related parties, have been eliminated upon consolidation and therefore do not require disclosure.

    The condensed consolidated financial statements for the six months ended 30 November 2025 and comparative period have not been audited. The interim financial report for the six months ended 30 November 2025 was approved by the Board on 2 February 2026.

3    Going Concern

In accordance with corporate governance requirements the directors have undertaken a review of forecasts and the Group's cash requirements to consider whether it is appropriate that the Group continues to adopt the going concern assumption.

The directors have reviewed the projected cash flow and other relevant information, including a 'severe but plausible' scenario and have a reasonable expectation that the Group has adequate resources to continue in operational existence and therefore it remains appropriate to adopt the going concern basis in preparing the interim financial report for the six months ended 30 November 2025.

4      Accounting estimates and judgements

    The preparation of the financial statements requires the use of accounting estimates and judgements that affect the application of accounting policies and reported amounts of assets and liabilities, income and expenses. The accounting estimates and judgements are continually evaluated and are based on historical experience and other factors, including expectations of the future that are believed to be reasonable under the circumstances. Actual results may differ from the expected results. Revisions to accounting estimates are recognised in the period in which the estimate is revised if the revision affects only that period, or in the period of the revision and future periods if the revision affects both current and future periods. The accounting estimates and judgements that have a significant effect on the financial statements are considered in the Filtronic plc Annual Report for the year ended 31 May 2025 which can be found on the Filtronic website. Unless stated below there is no material change to those judgements from the Annual Report in the basis of calculation.

5   Segmental Analysis

      Operating Segments

      IFRS 8 requires consideration of the identity of the Chief Operating Decision Maker ('CODM') within the Group. In line with the Group's internal reporting framework and management structure, the key strategic and operating decisions are made by the Board, who reviews internal monthly management reports, budget and forecast information as part of this. Accordingly, the Board is deemed to be the CODM.

      The CODM has identified one operating segment within the Group as defined under IFRS 8. In turn, this is the only reportable segment of the Group as the entities in the Group have similar products and services, production processes and economic characteristics. Therefore, there is no allocation of operating expenses, profit measures or assets and liabilities to specific commercial markets.

Accordingly, the CODM assesses the performance of the operating segment on financial information which is measured and presented in a manner consistent with those in the financial statements by reference to Group results against budget.

The Group profit measures are adjusted operating profit and adjusted EBITDA, both disclosed on the face of the consolidated income statement. No differences exist between the basis of preparation of the performance measures used by management and the figures in the Group financial statements.

5   Segmental Analysis (continued)

Revenue by Destination

The revenue presented is based on the geographic location of customers receiving the product/service from the continuing operations.

Revenue from sales

The revenue presented is based on the Group deriving revenue from product sales and those received from Non-Recurring Engineering ("NRE") at a point in time when the performance obligation is satisfied.

6   Operating profit

Development costs of £1,295,000 were capitalised in H1 2026 (HY2025: £486,000).

Other operating income relates to grants received for plant and machinery and R&D innovation whilst R&D tax credits under the new merged scheme are also recognised in operating profit.

7   Basic and diluted earnings per share

8    Contract assets

Contract assets relate to the share warrants issued to Space X.

9 Deferred income

Contract liabilities are invoices raised in advance of NRE work completed for customers that will be recognised as income once the performance obligation of the contract has been met. The majority of NRE contracts are invoiced with a proportion of the contract value upfront which is recognised as revenue, over time, across the life of contract at each milestone based on the percentage of the overall contract value achieved at that performance obligation.

10   Share Capital

All shares are allotted, called up and fully paid. Holders of the ordinary shares and entitled to retrieve dividends when declared and are entitled to one vote per share at meetings of the company.

11   Share Premium

12     Share Warrant Reserve

Tranche 1 and 2

On 24 April 2024, the Group entered into a share warrant arrangement with SpaceX in conjunction with a

commercial agreement and strategic partnership. This related to the supply of E-band Solid State Power Amplifiers ("SSPAs") and new technology being developed for SpaceX for use in their Starlink constellation.

The warrant agreement grants SpaceX the right to acquire up to 21,712,109 shares of the Company (equivalent to 10% of the Company's total share capital at the inception of the warrant agreement). The exercise price of vested warrants is 33.0p per share, based on the closing mid-market price at 23 April 2024, which is the date prior to signing the warrant agreement. The directors have assessed the warrants and made a judgement that the warrants should be treated as equity instruments as defined by IAS 32. This is because the warrants have a fixed consideration at 33.0p per share for a fixed number of units to exercise.

The warrants have been recognised in the financial statements based on the value at the date of signing of

the agreement. An initial entry has been made in contract assets measured at fair value, but not subsequently remeasured, with the corresponding entry to equity.

The initial fair value of the warrants at inception was £2,605,453, based on a fair value per warrant of £0.11 and the total number of warrants expected to vest over the 5-year vesting period. The directors have judged all of the warrants will vest, otherwise SpaceX and Filtronic would not have entered into the agreement. The warrants represent non-cash consideration payable to a customer under IFRS 15. Therefore, the contract asset, which effectively represents a deferred volume rebate, is amortised to revenue based on when the units are supplied to SpaceX.

The fair value of the warrants was determined using the Black-Scholes Model valuation method using a number of variables that require judgement including share price volatility, discount to the bid price, the risk-free rate and the expected life of the warrants. There are a number of variables that require judgement within this model including the risk-free rate, share price volatility, the vesting period and a bid price

discount.

Tranche 3

On 19 March 2025, the Company entered into a second warrant arrangement with SpaceX expanding the

Original strategic partnership entered into on 23 April 2024 to secure an increased allocation of business for the Group. The vesting of these warrants is dependent on certain performance conditions relating to the procurement of E-band SSPAs to support the Starlink constellation.

12     Share Warrant Reserve (continued)

The warrant agreement grants SpaceX the right to acquire up to 10,949,079 at 92.8p per share. The accounting treatment of the warrants has been judged by management and has been determined to be treated the same as tranche 1 and 2. An initial entry has been made in contract assets measured at fair value, but not subsequently remeasured, with the corresponding entry to equity.

The initial fair value of the warrants at inception was £3,504,000, based on a fair value per warrant of £0.93 and the total number of warrants expected to vest over the 5-year vesting period. The directors have judged all of the warrants will vest, otherwise SpaceX and Filtronic would not have entered into the agreement. The warrants represent non-cash consideration payable to a customer under IFRS 15. Therefore, the contract asset, which effectively represents a deferred volume rebate, is amortised to revenue based on when the units are supplied to SpaceX.

The fair value of the warrants was determined using the Black-Scholes Model valuation method using a number of variables that require judgement including share price volatility, discount to the bid price, the risk-free rate and the expected life of the warrants. There are a number of variables that require judgement within this model including the risk-free rate, share price volatility, the vesting period and a bid price discount.

13   Analysis of net cash

Cash at bank earns interest at floating rates based on daily bank deposit rates.

The Group entered into a financing arrangement in November 2024 with Santander UK plc for a committed £5.0m Revolving Credit Facility ("RCF") for three years. In December 2025, the Group extended this arrangement for a further three years and increased the facility to £10.0m.

There were no drawings on the RCF facility at 30 November 2025 (31 May 2025: undrawn).
